A new ternary complex [Ni(phen)(pmal)]·8H2O (phen = 1,10-phenanthroline, pmal2- = phenethyl malonic acid) has been synthesized by the reaction of nickel acetate, phen and phenethyl malonic acid. Elemental analysis, IR spectra and X-ray single-crystal diffraction were carried out to determine the composition and crystal structure. Crystal data for this complex: tric- linic system, space group P1, a = 10.387(5), b = 13.112(6), c = 14.229(6) , α = 76.176(7), β = 83.778(8), γ = 71.770(6)°, C35H42N4O12Ni, Mr = 769.44, Z = 2, F(000) = 808, V = 1786.1 3 , Dc = 1.431 g/cm3, μ = 0.612 mm-1, the final R = 0.0653 and wR = 0.1033 for 9379 (Rint = 0.0244) independent reflections and 4730 observed reflections (I > 2σ(I)). Structural analysis shows that the coordination geometry of Ni(II) is a distorted octahedron. A novel two-dimensional structure is constructed from (H2O)4 and (H2O)12 water clusters, and the complex forms a 3-D network supra- molecular structure by hydrogen bonds and π-π stacking of neighboring phens.

A novel two-dimensional structure is constructed from (H2O) 4 and (H2O) 12 water clusters, and the complex forms a 3-D network supra- molecular structure by hydrogen bonds and -π stacking of neighboring phens.
